Disclosed in the present invention are a cold box steel structure and method for prefabricating and transporting the cold box steel structure. The cold box steel structure is a cuboid architecture, and has a long edge, a wide edge and a high edge of lengths L, W and H respectively, wherein L&#x3e;W and L&#x3e;H; the cold box steel structure comprises first and second rectangular base faces, each being an outer surface of the cuboid architecture comprising the long edge and the wide edge, and the cold box steel structure is prefabricated as two partial components taking a plane parallel to the rectangular base faces as a boundary; the total height of a first partial cold box steel structure component thereof, taking the first rectangular base face as a first transportation bottom face, is h, and the total height of a second partial cold box steel structure component, taking the second rectangular base face as a second transportation bottom face, is h; if the height difference between the transportation bottom face and the ground or a water surface is h, then (h+h) corresponds to a transportation height of the first partial cold box steel structure component, and (h+h) corresponds to a transportation height of the second partial cold box steel structure component; the transportation height of either of the cold box steel structure components should be smaller than a maximum permitted transportation height h.

Cold box steel structure and method for prefabricating and transporting same

A process and apparatus for highly efficient production of industrial gases by the cryogenic distillation of air, wherein a feed stream of compressed air, is supercharged to high pressure, cooled, and mixed with various recycle streams of supercharged air, to regulate the expander turbine operating temperature. The need for pre-cooling equipment downstream of the supercharger, which is widely employed in industry to manage the temperature of the incoming compressed air stream, is eliminated.

Method and installation for producing, in gaseous form and under high pressure, at least one fluid chosen from oxygen, argon and nitrogen by cryogenic distillation of air

An apparatus and method for air distillation. Two cold boxes and an air treatment unit are used to distill air. The cold boxes contain a heat exchanger for cooling the air to be distilled and an air distillation unit for producing either oxygen, nitrogen or argon. The air treatment unit has many individual treatment elements which are connected in parallel. The outlet of the air treatment unit is connected to both cold boxes and to all the individual treatment units.

Production unit for large quantities of oxygen and/or nitrogen

In order to allow more flexible operation of a column for separating air by cryogenic distillation, a first air stream (6) exchanges heat with a liquid (16) which vaporizes, while a second air stream (7, 7A) is drawn off from an intermediate level in the exchange line and sent to a column in order to be distilled therein.
